What do you mean by "iffy"? My $200 x99 board has seperate IOMMU groups

or 1620v4, can do ACS and sane IOMMU groups with it for under $600 also,
without needing to get a used processor...
Personal experience - I have never seen a reasonably priced intel system that did it properly, whereas even AMD's "desktop" CPU's and chipsets have it.

I don't buy or recommend intel's stuff for exotic uses because I have been burned too many times by their artificial market separation efforts, I also do not like the fact that their newer products aren't owner controlled for a variety of reasons (although now you can say the same about AMD as well) which again isn't good for fringe uses as there is no ability to fix things that the board vendor refuses to.

There isn't anything wrong with buying a used processor, and $150 gets you a 6386SE with 16 cores.
